I'd say ignorance is no excuse, but oh well. You now know which is the most important thing.
He has been changed yes, but he's been changed in such a way that instead of feeling like a clone of Cpt. Falcon, he basically took those similiarities and made them his own. By For., his neutral attack, tilts, up smash, forward aerial, up-throw, and side special are unique, down smash, down aerial, and Warlock Punch were visually altered, and Dark Dive was also altered to have an attack independent of the grab motions, while Wizard's Foot got a meteor smash effect at the start of the aerial version. His custom specials are also all different from the Captain (though one makes his Side Special resemble his old Side Special move and Cpt. Falcon's by proxy... though having a custom alter the properties of a special to become more like the parent character is a recurring thing with all characters that are semiclones with someone.)
